Stroke; a journal of cerebral circulation

Recently, a combined repetitive transcranial magnetic stimulation (rTMS) and activation positron emission tomography (PET) study showed essential language function of the right inferior frontal gyrus (IFG) in some right-handed acute poststroke aphasics. We reexamined these patients in the chronic phase to test whether the right IFG remained essential for language performance. ⋯ Successful regeneration from poststroke aphasia seems to depend more on the integration of available language-related brain regions than on recruiting new brain regions during the rehabilitation process. Restoration of the left hemisphere network seems to be more effective, although in some cases, right hemisphere areas are integrated successfully.

Stroke patients often report that primary care physicians (PCPs) are their first medical contact after onset of symptoms. We studied PCP attitudes and current practice in early management of suspected stroke patients. ⋯ Stroke and transient ischemic attack were well recognized as medical emergencies by PCPs in our study. However, only two-thirds of PCP would immediately admit stroke suspected patients with clear symptoms to hospital as medical emergency.

Apolipoprotein E (apoE) alleles (epsilon2 and epsilon4) are associated with cerebral amyloid angiopathy, in which white matter disease and microbleeds are prominent features. The role of apoE in patients with microbleeds or white matter disease but no evidence of cerebral amyloid angiopathy has not been elucidated. We studied apoE alleles in relation to white matter disease and microbleeds in patients with transient ischemic attack or ischemic stroke. ⋯ ApoE alleles do not exert a major influence on the development of microbleeds, but apoE epsilon2 may be associated with development of moderate to severe white matter disease in transient ischemic attack and stroke patients.

Basilar artery occlusion (BAO) is a stroke subtype with poor prognosis, but recanalizing therapies have been reported to be effective. We investigated whether initial admission to telemedically linked general hospitals with subsequent stroke-center transfer is related to poorer outcome than direct admission to stroke centers. ⋯ BAO patients who were admitted primarily to community hospitals had a worse prognosis. Patients with typical symptoms should have direct access to stroke centers, or may need bridging therapies.

Weekend admissions are associated with higher in-hospital mortality. However, limited information is available concerning the "weekend effect" on stroke mortality. Our aim was to evaluate the impact of weekend admissions on stroke mortality in different settings. ⋯ Stroke patients admitted on weekends had a higher risk-adjusted mortality than did patients admitted on weekdays. Disparities in resources, expertise, and healthcare providers working during weekends may explain the observed differences in weekend mortality.
